Tekken 5: Dark Resurrection(鉄拳5ダーク復活,Tekken 5: Dāku Fukkatsu?) is: a one-on-one fighting arcade game which was released by Namco in 2005; it runs on the company's System 256 hardware, and is the seventh title for the Tekken series. It is also the company's second update of Tekken 5 (the first being Tekken 5.1, which was released earlier in 2005, and changed the characters' move lists as well as its "wall system") - but this one also features two new characters, Émilie "Lili" de Rochefort, and Sergei Dragunov. When Eighting redeveloped the game for the Sony PlayStation Portable, they dropped the 5 from its name; this version was initially released in Japan on July 6, 2006 (and later for the US, Australia and the EU on July 25, September 14 and September 15 of that same year). Three months after the PSP version had been released in the EU on December 12, it was also released on the PlayStation Network in Japan (later released for the US on March 1, 2007, and for both Australia and the EU on March 23 of that same year) - and as with the original Tekken 5, it is also possible for players to bring their PlayStation 2 controllers from home and plug them into the ports of the cabinet.
